RPM方式安装MySQL5.6

1.检查MySQL及相关RPM包

检查MySQL及相关RPM包，是否安装，如果有安装，则移除(rpm –e 名称)[root@localhost ~]# rpm -qa | grep -i mysql

mysql-libs-5.1.66-2.el6_3.x86_64

[root@localhost ~]# yum -y remove mysql-libs*

2.下载rpm包

下载Linux对应的RPM包，如：CentOS6.4_64对应的RPM包，如下：[root@localhost rpm]# ll

total 74364

-rw-r--r--. 1 root root 18442536 Dec 11 20:19 MySQL-client-5.6.15-1.el6.x86_64.rpm

-rw-r--r--. 1 root root 3340660 Dec 11 20:06 MySQL-devel-5.6.15-1.el6.x86_64.rpm

-rw-r--r--. 1 root root 54360600 Dec 11 20:03 MySQL-server-5.6.15-1.el6.x86_64.rpm

3. 安装MySQL[root@localhost rpm]# rpm -ivh MySQL-server-5.6.15-1.el6.x86_64.rpm

[root@localhost rpm]# rpm -ivh MySQL-devel-5.6.15-1.el6.x86_64.rpm

[root@localhost rpm]# rpm -ivh MySQL-client-5.6.15-1.el6.x86_64.rpm

#修改配置文件位置

[root@localhost rpm]# cp /usr/share/mysql/my-default.cnf /etc/my.cnf

4. 初始化MySQL及设置密码[root@localhost rpm]# /usr/bin/mysql_install_db

[root@localhost rpm]# service mysql start

[root@localhost rpm]# cat /root/.mysql_secret #查看root账号密码

# The random password set for the root user at Wed Dec 11 23:32:50 2013 (local time): qKTaFZnl

[root@localhost ~]# mysql -uroot –pqKTaFZnl

mysql> SET PASSWORD = PASSWORD('123456'); #设置密码为123456

mysql> exit

[root@localhost ~]# mysql -uroot -p123456

5. 允许远程登陆mysql> use mysql;

mysql> select host,user,password from user;

+-----------------------+------+-------------------------------------------+

| host | user | password |

+-----------------------+------+-------------------------------------------+

| localhost | root | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9 |

| localhost.localdomain | root | *1237E2CE819C427B0D8174456DD83C47480D37E8 |

| 127.0.0.1 | root | *1237E2CE819C427B0D8174456DD83C47480D37E8 |

| ::1 | root | *1237E2CE819C427B0D8174456DD83C47480D37E8 |

+-----------------------+------+-------------------------------------------+

mysql> update user set password=password('123456') where user='root';

mysql> update user set host='%' where user='root' and host='localhost';

mysql> flush privileges;

mysql> exit

6. 设置开机自启动[root@localhost ~]# chkconfig mysql on

[root@localhost ~]# chkconfig --list | grep mysql

mysql 0:off 1:off 2:on 3:on 4:on 5:on 6:off

7. MySQL的默认安装位置

/var/lib/mysql/ #数据库目录

/usr/share/mysql #配置文件目录

/usr/bin #相关命令目录

/etc/init.d/mysql #启动脚本

8.修改字符集和数据存储路径

配置/etc/my.cnf文件,修改数据存放路径、mysql.sock路径以及默认编码utf-8.

[client]

password = 123456

port = 3306

default-character-set=utf8

[mysqld]

port = 3306

character_set_server=utf8

character_set_client=utf8

collation-server=utf8_general_ci

#(注意linux下mysql安装完后是默认：表名区分大小写，列名不区分大小写； 0：区分大小写，1：不区分大小写)

lower_case_table_names=1

#(设置最大连接数，默认为 151，MySQL服务器允许的最大连接数16384; )

max_connections=1000

[mysql]

default-character-set = utf8

9.查看字符集show variables like '%collation%';

show variables like '%char%';
